FAQ

What is the lug width of the Vacheron Constantin Métiers d'Art 17620/S11G-9478?

The Vacheron Constantin Métiers d'Art 17620/S11G-9478 is fitted with an 18mm lug width. This measurement refers to the internal distance between the two lugs of the white gold case and determines the exact width of the compatible strap. To verify it, use a digital caliper positioned internally between the lugs, not on the external width of the case.

What is the best strap for the Vacheron Constantin Métiers d'Art 17620/S11G-9478?

For the Métiers d'Art 17620/S11G-9478 with white gold case, an alligator strap — Mississippi or Porosus — is the choice most consistent with the decorative identity of the piece. The symmetrical grain of the scales dialogues with the reflections of white gold, in both polished and matte versions. Box-calf leather represents an alternative with a more everyday character, capable of developing an authentic patina over time. The buckle or deployante should be in white gold or brushed steel.

How do you change the strap on the Vacheron Constantin Métiers d'Art 17620/S11G-9478?

The strap is removed by acting on the spring bars that connect the strap to the case lugs. For a white gold watch of this caliber, it is strongly recommended to entrust the work to a specialized watchmaker or to the Casati Milano atelier, using tools with Teflon or soft rubber protections to avoid any scratching on the polished surfaces of the case.

Are there aftermarket straps compatible with the Vacheron Constantin Métiers d'Art 17620/S11G-9478?

Yes. Any artisanal 18mm strap with standard spring bars is technically compatible with the Vacheron Constantin Métiers d'Art 17620/S11G-9478. Milano Straps offers a selection of 18mm straps in fine leather and technical materials handcrafted, compatible with this reference. For a bespoke result, the Casati Milano atelier creates custom straps by choosing leather, stitching, and buckle based on the specific characteristics of the watch.

How long does a leather strap last on a Vacheron Constantin Métiers d'Art 17620/S11G-9478?

The lifespan of a leather strap depends on the material, frequency of use, and care given to the piece. A high-quality alligator strap, used with care — avoiding prolonged exposure to moisture, sweat, and direct light — can last between 3 and 7 years while maintaining a dignified patina. Box-calf leather tends to develop creases more quickly in areas of intense flexion. Casati Milano straps are covered by an 18-month warranty against manufacturing defects.
